Upwelling, offshore transport, and the availability of rockfish in central California
EXTRACT (SEE PDF FOR FULL ABSTRACT):We used the diet of a seabird, the common murre (Uria aalge), nesting on Southeast Farallon Island and feeding in the Gulf of the Farallones, California, as an index to abundance of juvenile rockfish, then related fish abundance to indices of turbulence and upwell...
